ATTACHMENT FOR INTERNAL-COMBUSTION ENGINES.

To all whom it may concern c Be it known thatI, LOUIS P. PETERSON, a citizen of the United States, residin Enderlin, in the county of Ransom and tate of North Dakota, have invented certain new and useful Improvements in Attachmentsv 'for Internal-Combustion Engines, of which the following is a specification.

This lnvention relates to attachments for internal combustion engines which supply a.

small quantity of water to mix with the comconstruction and combination of the parts hereinafter fully described and claimed.

'In the drawings, Figure 1 is a side view} of an attachment constructed according to this invention. Fig. 2 is V a cross-section tihrough the device, taken on the line 2-2 inig. 1. i

A supply pipe 3 for water is provided and communicates with a needle valve 4 arranged vertically in a valve casing 5. A cylindri-. cal observation chamber '6 is secured axially under the lower end of thevalve casing 5," and is provided with a window? of glass or other transparent material. Asecond needle valve 8 is arranged horizontally in avalve casing 9 which is secured to the lower part of the observation chamber 6. The valve casing 9 is provided with means for securing it to the engine, such as the screwthreaded portion 10. a The valve casings and observation chamgreat exactness.

. What I ClfiJIIl lSZ her are air-tight, andthe valve casing 9 is secured to any part of the engine whlch 1s subjected to thesuction caused by the piston j of the power cylinder drawing in the'inflammable charge of air and hydrocarbona The use of a small quantity of water is desirable to prevent carbon deposits in the cylinder, and for other purposes, and the employment. of the two adjustable needle valves arranged'as set forth enables the supply of water to be proportioned with A'moistening'attachment for an internal combustion engine, comprising an upper valve casing provided with an inlet for water and a vertically arranged outlet, a needle valve controllingthe said outlet, an observation'chamber secured to the lower end of the upper valve casing and provided with'a sight window, a lower valve casing falls'drop bydrop through the observation chamber, said lower valve casing being secured to the lower part of the observation chamber and provided with ahorizontally arranged outlet for water and with means In testimony whereof I have aflixed my 65 signature.
